Preparation method of Ti < 3 + > self-doped TiO2 supported activated carbon photocatalytic material

The invention relates to a preparation method of a Ti < 3 + > self-doped TiO2 supported activated carbon photocatalytic material. The preparation method comprises the steps that absolute ethyl alcohol, tetrabutyl titanate and nitric acid are taken as reaction raw materials, nano activated carbon is added in the reaction process to serve as an active carrier, the Ti < 3 + > self-doped TiO2 catalyst is generated, and through improvement of the preparation method, the prepared catalyst has the advantages that self-doped Ti < 3 + > is more, the activity is better, a good coupling effect is generated between the active component and the activated carbon, and the prepared catalyst has good adsorption and photocatalytic decomposition effects on rhodamine B dye under an ultraviolet light condition. 本发明涉及一种活性炭负载TiO2自掺杂Ti3+的光催化材料的制备方法，属于光催化材料技术领域，本发明以无水乙醇、钛酸四丁酯、硝酸为反应原料，并在反应过程中加入纳米活性炭作为活性载体，不仅生成了自掺杂Ti3+的TiO2催化剂，且通过制备方法的改进，使生成的自掺杂Ti3+更多，活性更好，且活性成分与活性炭中间产生很好的耦合作用，所制备出的催化剂在紫外光条件下对罗丹明B染料具有良好的吸附和光催化分解作用。
